How Old is the Earth SCIENTIFIC AGE OF THE EARTH. efore analyzing the arguments advanced by creation “scientists” for a very young Earth, I here summarize briefly the evidence that has convinced scientists that the Earth is 4.5 to 4.6 billion years old.

- Nobody discovered earth, in the sense that European Explorers were said to have discovered. The Americas and Australasia. Planet Earth formed over 4 billion years ago and… life first formed about 1 billion years later. The first Human life as we understand it today originated about 200,000 years ago so it could be said that those early humans discovered the planet. Regrettably, there is no record of any of their names.

Age of the Universe Six Days. We look back in time, and say the universe is approximately 15 billion years old. But every scientist knows, that when we say the universe is 15 billion years old, there's another half of the sentence that we never say.

How Old is the Earth The third approach, and the one that scientists think gives the most accurate age for the Earth, the other planets, and the Solar System, is to determine model lead ages for the Earth, the Moon, and meteorites.

- It is not possible to be certain how life on Earth began. We do know that: 1  the Earth is about 4,500 million years old.  there is evidence that living things existed on Earth at least 3,500 million years ago.

Young Earth creationism The common belief of Young Earth Creationists is that the Earth and life were created in six 24-hour periods, 10,000–6,000 years ago. However, there are different approaches to how this is possible given the geological evidence for much longer timescales.oung Earth creationists differ from other creationists in that they believe in a strict literal interpretation of the Bible regarding the age of the Earth.

Geologic Time Scale The age of the Earth now is estimated to be between 5 billion and 4.7 billion years and estimates of the duration of the geologic time scale divisions have been made.

How Science Figured Out the Age of Earth And the oceans have long since approached something close to a steady state, with chemical sediments removing dissolved minerals as fast as they arrive. Nevertheless, by the late 19th century the geologists included here had reached a consensus for the age of the earth of around 100 million years.

- He took them to the Argonne National Laboratory, where he was granted time on a late-model mass spectrometer. In a meeting in Wisconsin soon afterward, Patterson revealed the results of his study. The definitive age of the Earth is 4.550 billion years (give or take 70 million years). The current estimate for the age of the earth is 4.54 ± 0.05 billion years (4.54 × 109 years ± 1%).

- (scientific methods). 1  In 1897, Lord Kelvin assumed that the Earth was originally molten and calculated a date based on cooling through conduction and radiation. 2  The age of Earth was calculated to be about 24-40 million years based on the laws of thermodynamics.

- Most physicists believe the earth is 4.5 billion years old. And the results of Terra, run with that assumption, works out OK. On the other hand, run the program assuming the earth is less than 10,000 years old, and that there was a catastrophic universal Flood, and all the geology works out OK that way also!

The Age of the Earth he generally accepted age for the Earth and the rest of the solar system is about 4.55 billion years (plus or minus about 1%). This value is derived from several different lines of evidence. Unfortunately, the age cannot be computed directly from material that is solely from the Earth. There is evidence that energy from the Earth's accumulation caused the surface to be molten. Further, the processes of erosion and crustal recycling have apparently destroyed all of the earliest surface.

Scientists and Belief Meanwhile, younger scientists (ages 18-34) are more likely to believe in God or a higher power than those who are older.

The Biblical Age of the Earth This idea has only become popular within the last 200 years or so. Prior to the early 1800’s and late 1700’s most people believed the biblical age of the earth, about 6,000 years old, as recorded in the Bible. They took God’s word as truth.

How did planet Earth form? The age of Earth is approximately one-third of the age of the universe. An immense amount of geological change has occurred in that timespan, accompanied by biological change. Earth formed around 4.54 billion years ago by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean; but the atmosphere contained almost no oxygen and so would have been toxic to most modern life including humans.

- The age of Earth was calculated to be about 24-40 million years based on the laws of thermodynamics. Unknown at the time was that the Earth has an internal heat source (radioactive decay) In 1899, John Joly (Irish) calculated the rate of delivery of salt to the ocean.

James Hutton  (1726-1797) James Hutton (1726-1797) Being the first person to think of the Earth as millions of years old. Farmer and naturalist James Hutton is credited with being the founder of modern geology. The first to determine that the Earth is millions of years old, Hutton believed our planet is continually being formed.

The Age of the Earth and the Formation of the Universe Honors Seminar (UHON 390), Fall 2005 By Peter Fischer. The continents erode too quickly for the Earth to be any older than 15-16 million years. This is but one of the many claims that some Young-Earth Creationists have used in contention to the scientific community's established view that the Earth is roughly 4.5 billion years old (Dalrymple 2004: 1).

- Nevertheless, scientists have been able to determine the probable age of the Solar System and to calculate an age for the Earth by assuming that the Earth and the rest of the solid bodies in the Solar System formed at the same time and are, therefore, of the same age.

Other Evidence for a Young Earth and Universe They also believe that the earth is approximately 3 to 5 billion years old. The most obvious explanation for a young earth and universe is superluminal Superluminal speed is faster than the speed of light. speed and decay of the speed of light over the last 6,000 years.

The Earth forms The Earth is thought to have been formed about 4.6 billion years ago by collisions in the giant disc-shaped cloud of material that also formed the Sun. Gravity slowly gathered this gas and dust together into clumps that became asteroids and small early planets called planetesimals.

The Age of the Earth and the Formation of the Universe Honors Seminar (UHON 390), Fall 2005 Creationists need to account for why there appears to be a geologic and fossil record of containing billions years of history if the earth and universe are actually only a few thousand years old. Most of the arguments made by creationists try to discount various dating methods used by scientists.

Age of the Earth In 1895, John Perry produced an age-of-Earth estimate of 2 to 3 billion years using a model of a convective mantle and thin crust. Kelvin stuck by his estimate of 100 million years, and later reduced it to about 20 million years.

Continental Drift and Seafloor Spreading Until only recently, geologists had thought that Earths surface hadnt changed much since the planet formed 4.6 billion years ago. They believed that the oceans and continents were always where they are now. But less than 100 years ago, a German scientist named Alfred Wegener took notice of some interesting findings. Similar plant and animal fossils were found in both Africa and South America and on other continents separated by oceans. Similar rock formations were also found on distant continents.
